for any length of time without its quality deteriorating.
LPG is entirely free of poisonous substances.
The risk with gas is that leaking gas is ignited, resulting
in an explosion. As LPG has no distinct aroma, sulphur
compounds are added that give a distinct, pungent
smell, even when the concentration of gas is as low as
one fth of the lower explosion limit. The LPG burner
usually works at a lower pressure than the pressure in
the cylinder. Low pressure is obtained by allowing the
LPG to pass through a regulator.
TROUBLESHOOTING7.
Here is a brief troubleshooting chart that may be of
help in the event of simple faults.
The ignition spark comes but the boiler does
not start
Check gas supply.1.
Is the service tap fully open?2.
If the boiler has been out of use for a while or if the 3.
gas cylinder has been changed, it takes longer to
ignite than normal.
The thermostat knob must be pushed down as far 4.
as it will go when starting.
If this does not help, contact your service workshop.5.
No ignition spark
Check that there is a 12-volt supply to the boiler.1.
Check the fuse on the boiler is intact.2.
Check that the warning light for the ignition spark is 3.
ashing.
Remove the lower front cover. Check that the ca-4.
bles to the ignition transformer (small black box just
under the control panel) and the microswitch (under
the thermostat) are properly attached and that there
is no corrosion on the cable clips.
If this does not help, contact your service workshop.5.
The boiler ignites but goes out when the ther-
mostat knob is released
Repeat the ignition procedure as per instructions 1.
in chapter 2:2 (wait 3 minutes before igniting the
boiler again). Make sure that the thermostat knob is
pushed down as far as it will go and hold it in posi-
tion for 20-30 seconds after the warning light has
gone out.
Check that the pilot ame comes into contact with 2.
the tip of the thermoelement (to the right of the pilot
burner).
If this does not help, contact your service workshop.3.
The boiler boils
Turn the thermostat knob to 1 (lowest system tem-1.
perature) and check that the main ame goes out,
as it should.
Check that the sensor is secured correctly. It should 2.
be attached to the body of the boiler by a spring
clip just under the control box with heat-conducting
putty in between.
If this does not help, contact your service workshop.3.
Vibrations in the circulation pump (12volt)
Release the nut holding the circulation pump.1.
Turn the pump a little and tighten up the nut again.2.
Check that the rubber connection between the 3.
motor and the shaft is straight and does not wobble
when in motion.
Check that there is no obstruction in the way of the 4.
pump at the bottom of the expansion vessel.
If this does not help, contact your service 5.
workshop.
Noise in the motor of the circulation pump
(12volt)
Drop a drop of sewing machine oil into the centre 1.
hole at the top of the motor.
If the noise does not disappear or returns after a 2.
while, the motor should be replaced.
Circulation pump (12volt) will not start
Check that the slider on the room thermostat is in 1.
”ON” position.
Check that the temperature shown on the room 2.
thermostat is higher than inside the vehicle.
Check that the changeover switch on the control 3.
panel for the circulation pump is on ”12-volt pump”.
Remove the circulation pump and check that the 4.
cables are properly secured, and that there is a 12-
volt supply.
If this does not help, contact your service 5.
workshop.
Incorrect temperature on the room thermostat
Check by using an accurate thermometer inside the 1.
vehicle.
Remove the cover from the room thermostat (press 2.
in the pin on the left-hand side and pull the cover
straight out).
Pull out the knob and move it as many degrees up 3.
or down as it indicated wrongly, and press it into
place again.
Replace the cover and check that the temperature 4.
agrees with the scale on the room thermostat.
The immersion heater has stopped working
Check that there is power (230/240 volts) in the 1.
wall socket.
Check that the relays on the immersion heater 2.
switch on (a gentle click should be heard).
Check whether the overheating protection has trig-3.
gered. If so, press in the button on the side of the
cover.
If this does not help, contact the service workshop.4.
